Dyshidrotic Eczema: Symptoms, Causes, and Treatment Options
Dyshidrotic eczema is a form of eczema that often catches people off guard. It tends to appear suddenly, looks different from typical eczema rashes, and is frequently mistaken for fungal infections, allergies, or contact dermatitis. Because of this, many people delay proper care, allowing symptoms to worsen.
Understanding what dyshidrotic eczema looks like, what triggers it, and how it can be managed is key to keeping flare-ups under control and protecting your skin in the long term.
What Is Dyshidrotic Eczema?
Dyshidrotic eczema is a chronic skin condition that mainly affects the hands and feet. It is characterised by small, fluid-filled blisters that develop beneath the surface of the skin.
Where it commonly appears
This condition most often shows up on:
-
Fingers and palms
-
Sides of the hands
-
Soles of the feet
-
Toes
The blisters are usually symmetrical and can appear on both hands or both feet at the same time.
How it differs from other eczema types
Unlike classic eczema, which often causes dry, scaly patches, dyshidrotic eczema begins with blisters. These blisters can be painful or intensely itchy and may lead to peeling and cracking as they heal.

Common Symptoms of Dyshidrotic Eczema
Small blisters
The most recognisable sign of dyshidrotic eczema is clusters of tiny blisters. They may look like bubbles under the skin and are often deep-seated rather than surface-level.
Itching, burning, and peeling
Many people experience intense itching or a burning sensation before blisters even appear. As the blisters dry out, the skin may peel, crack, or feel extremely dry.
How flare-ups progress
Flare-ups often start suddenly, peak within a few days, and then slowly improve over one to three weeks. Without proper care, repeated flare-ups can weaken the skin barrier over time.
What Causes Dyshidrotic Eczema?
There is no single cause, but several factors are known to trigger or worsen dyshidrotic eczema.
Stress
Emotional and physical stress is a well-known trigger for dyshidrotic eczema. During stressful periods, the body releases hormones that can weaken the skin barrier and increase inflammation. Many people notice flare-ups during times of high work pressure, emotional strain, fatigue, or poor sleep. Long-term stress may also slow skin healing, making symptoms last longer.
Heat and Sweating
Warm, humid conditions and excessive sweating can aggravate dyshidrotic eczema, especially on the hands and feet where moisture can become trapped. In climates like Singapore’s, frequent sweating may soften the skin and weaken its natural protective barrier. This makes it more vulnerable to irritation, blister formation, and repeated flare-ups.
Allergens and Irritants
Regular exposure to harsh soaps, detergents, cleaning products, sanitisers, or certain metals such as nickel can irritate sensitive skin and trigger symptoms. Repeated handwashing and contact with chemicals may strip away natural oils, leaving the skin dry and inflamed. Over time, this ongoing irritation can increase the frequency and severity of flare-ups.
Genetic or Skin Sensitivity Factors
People with a personal or family history of eczema, asthma, hay fever, or generally sensitive skin may be more prone to developing dyshidrotic eczema. These individuals often have a weaker skin barrier and a heightened immune response, making their skin more reactive to environmental triggers. As a result, flare-ups may occur more easily and require consistent long-term management.
Dyshidrotic Eczema Treatment Options
Managing dyshidrotic eczema usually focuses on calming symptoms, supporting the skin barrier, and reducing triggers. The right dyshidrotic eczema treatment can vary from person to person.
a. Topical treatments
Creams and ointments are commonly used to soothe dryness, reduce discomfort, and support skin recovery. Non-irritating formulations are especially important, as compromised skin can react easily to fragrances, alcohol, or harsh active ingredients.
b. Lifestyle and trigger management
Simple habits can make a meaningful difference. Gentle hand care, regular moisturising, and avoiding known irritants help reduce stress on the skin and lower the risk of flare-ups.
How to Manage Flare-Ups Long-Term
Consistent skincare
Maintaining a daily skincare routine, even when the skin appears clear, helps strengthen the skin barrier and reduce future flare-ups.
Stress management
Because stress is a known eczema trigger, techniques such as regular breaks, relaxation exercises, or improved sleep routines can support overall skin health.
Early intervention tips
Addressing early signs such as itching or dryness may help prevent a full flare-up. Applying suitable products early can support faster recovery.
Conclusion
Dyshidrotic eczema can be uncomfortable and frustrating, but early recognition and proper care make a significant difference. By understanding the symptoms, identifying triggers, and following a consistent dyshidrotic eczema treatment approach, many people are able to manage eczema flare-ups more effectively and maintain healthier skin over time.
